As a source told the magazine, Selena "always saw the best" in Justin, even throughout his many legal troubles and their own on-again, off-again relationship. "Justin was Selena's first love. He will always have a special place in her heart. She's always held out hope that one day the circumstances and timing would be right," the source added. "There have been times in the past where Selena was excited and thought things would work out again, but then was disappointed [by how things turned out]."

Another insider told People that Justin has also never been able to get over Selena and is currently on his best behavior in an effort to try to win her back. "They're having a great time together. Neither are seeing anyone else and they seem happy to leave it at this for now," the source said. "Spending time together makes them both very happy. For Justin, no one ever came close to comparing to Selena. He always thought she was the most special, and now seems mature enough to realize Selena deserves the best."

Selena, 25, and Justin, 23, who dated on and off between 2011 and 2014, were first spotted hanging out again last month. At the time, sources said Justin had reached out after hearing about Selena's kidney transplant, and that the pair had reconnected while attending the same church. Not long after, however, Selena and The Weeknd broke up after 10 months of dating, and the rumor mill kicked into high gear, with many reporting that the two pop stars were actually more than friends (to Selena's family's dismay).
